How to make a generic function for WMI query?

[John C.]

I am trying to make a generic function for WMI query by substituting the property's name using a variable. However, AutoIT3 always returns syntax error. The problem is how to let autoit treats '.' differently.

WMIQuery("CIMV2","Win32_PerfFormattedData_TermService_TerminalServices","TotalSessions,ActiveSessions")

Func WMIQuery($NameSpace,$path,$Properties)
    Local $output
    $Properties = StringSplit($Properties, ',')
    $objWMI = ObjGet("winmgmts:{impersonationLevel=Impersonate}!\\localhost\Root\" & $NameSpace)
    If Not IsObj($objWMI) Then 
        ConsoleWrite("Error accessing name space" & @LF)
        Exit
    EndIf
    
    $objCol = $objWMI.ExecQuery("Select * from " & $path)

    For $obj In $objCol
        For $i = 1 to $Properties[0]
            $output = $obj.TotalSessions ;This line works
            ;$output = ($obj.$Properties[$i])  ;cause syntax error
            ;$output = ($obj & '.' & $Properties[$i]) ;No return. How to make this line work?
            ;debug ConsoleWrite($Properties[$i] & @LF)
        Next
    Next
    ConsoleWrite($output & @LF)
EndFunc

I think you might be looking for Execute():

$output = Execute("$obj." & $Properties[$i])
